chautemoc: Well, not to you. I notice improvement on Win7 and enjoy using it much more. Have not had trouble. But it is preference...
Well I don't know about about Win7 but my 1 year experience of fixing and solving broblems with my goddaughter's laptop has been horrible to say the least. I believe many of the problems stem from entirely broken UAC as it seem to have been (silently I may add) blocking installation of MS own Windows Live!
Originally about a year ago when my sister bought it for her daughter I tried to install Windows Live (due to MS messager having been integrated to it) but it failed. Problem was there was no error message and installation seemed to go properly from start to finnish but the program icon took me to windows live page as it had been originally and windows update still offered it for download. I tried manual download and install but ran into excact same problem. Running installer as administrator did not work either. I disabled firewall and antivirus - no go. I tried other things as well but nothing worked at the end (I was not aware of UAC at the time and no one mentioned it when I asked.) so I gave up at the time.
Similar problems cropped up over the months with installations and running various programs until few months back I tried disabling UAC as suggested in the internet and you know what? Windows live installed properly straight away (the install process was exactly same except now it actually got installed). I've also not have serious problems with installation or running any applications since (haven't tried any games however). Funny part of the problems is that almost all of the applications I've had installed before were commercial and all had compatible with Vista certification :P and UAC never gave even a beep during any of the installations (it did popup while running some however) so there was no way of knowing what the problem was.
There have been less problems after that but I haven't been asked to install any new prorams so I just have to keep fingers crossed as I've lost too much hair due to that piece of junk OS already. I've probably delt with more problems in single year on that one laptop than on every other computer I've owned or maintained durring my entire life. IMHO the people who developed that abomination should be shot for the good of humanity.
So I hope you don't mind me being a bit negative about Vista on occasion :P ( You do know that VISTA is short of 'Viruses, Infections, Spyware, Trojans, Adware'?) ;) :D
